What is GB-115?
GB-115 (CAS 678996-63-9) is a small dipeptide-based compound from the Zakusov Institute of Pharmacology in Moscow. It was designed as an analog of the anxiety-linked peptide CCK-4.
It’s sold in Russia under the name Ranquilon.

Research on GB-115
Russian rodent studies report anxiolytic effects in standard tests like the elevated plus maze, without the sedation seen with benzodiazepines.
Most of the data are published in Russian.
The original papers are on PubMed if you’d like to read them in full.
How to use the GB-115 liquid
The liquid form saves you the work of dissolving powder. GB-115 is already in solution at 5mg/mL, so every millilitre holds the same amount. A 1mL draw gives you 5mg.
Use a clean graduated pipette or dropper for each draw so nothing goes back into the bottle. Shake gently first, because some solutions settle over time. We stock transfer pipettes and dropper bottles if you need them.
Making working dilutions of GB-115
If your protocol calls for a lower concentration, dilute a measured volume into a clean glass bottle. For example, 1mL of the 5mg/mL solution plus 1mL of carrier gives 2mL at 2.5mg/mL. Use the same carrier where possible, or a solvent your protocol allows, and mix gently.
Make up only what you’ll use in the short term, and label the new bottle with the concentration and date.
GB-115 quality and testing
We test each batch of GB-115 by LC-MS, which pairs liquid chromatography with mass spectrometry. The chromatography splits the sample into its components and the mass spectrometer identifies them, which tells you both identity and purity. This batch came in at 99% or higher.
Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.
Storage and handling
Keep it sealed in a cool, dry place away from light. Keep the cap tight so the solution doesn’t evaporate or pick up contaminants. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
